SPECIFICATION forming part of Letters Patent No. 590,8'15, dated.september 2s, 1897.

Application filed July 8,'189. I Serial No. 598,375. (No model.)

To @ZZ lull/omit Indy concern:

Be it known that We, GEORGE S. BARROWS' and WILLIAM ELIOT BARRovvs,citizens ofthe United States, lresiding at the city of Phila-:f delphia,in the county of Philadelphia and State of Pennsylvania, have inventedcertain new and useful Improvements in VVelsbach or.. other Lights, ofwhich the following is a speci-y fication.

One object of our invention is to provide an atmospheric burner in whichthe burner-y cap may be moved into any required posit-ion independentlyof the base, which may be fixed.

Another object of our invention is to protect the mantles or hoods ofWelsbach and other incandescent lights from shocks and vibrations suchas tend to their injury.

Other objects of our invention, as Well as the nature, characteristicfeatures, and scope thereof, will be more fully understood from thefollowing description, taken in connection with the accompanyingdrawing, forming part hereof, and in which is illustrated,` partly inelevation and partly in central section, apparatus embodying features ofour invention.

In the drawing a iiexible Bunsen tube c', as rubber or the like, isinterposed between the burner-cap h and the base c, which mayV be andusually is attached to the gas-pipe d of a fixed bracket, chandelier, orother supply of gas. To complete the Bunsen burner, air may be supplied,as at e, and use may be made of a gas-check, as f. The hood or mantle gis sustained by an elastic support, and is shown as connected with amantle-carrier h, which suspends it over the burner-cap b.

In the embodiment of our invention shown in the drawing the mantle andits carrier h are sustained by elastic supports t', for eX- ample,throughthe intervention of a gallery y .7., having a spider j, to whichthe carrier 7L and cap b are connected.

The elastic supports c' may consist simply of springs or other elasticbodies, or they may consist of springs and articulated portions formingchains i.

As shown in the drawing the burner-ca y Z2 is fitted to an aperture inthe spiderj, and is provided With a gasket or centrally-perfo-- ratedwasher bfor example, of asbestos or `the l'ike-and with a dependingsleeve or skirt hQfor example, also of asbestos or the likewhichaccommodates the upper end of the iieXible Bumsen tube c in such mannerthat clearance is'afforded between the top of the tube and the part b.

7c is a weight applied to the mantle-carrier 7L or to some partconnected therewith, and for theY sake of description it is shown asapplied to the gallery j.

Z is'a chimney mounted'upon the galleryj.

In'use the iiexible Bunsen tube c permits the burner-cap ZJ and partsconnected therewith to occupy any required position or positions inrespect to the `base c, which is usually ixed,'while at the same timethis flexible tube @supplies through itself a mixture of gas and air forproducing a Bunsen iiame Aoutside of the cap l). Moreover, the flexibleBunsen tube interposed between the base and `Cap presents a Vsiglitlyand neat appearance.

The locationof the tube c above the air-inlets causes it fto operateboth as a Buvnsen tube and asa flexible gas connection. By thus makingone part do the work of two the height of thebu'rner is comparativelysmall, no greater than in an ordinary fixture or light, whereby anattractive appearance is presented. The elastic supportsxi at their freeends are connected with a suitable fixture (not shoWn)-for example, tothe ceiling or to a framework or lantern carried by the part d. Unduevibrations are compensated for by these elastic supports, and hence arenot transmitted to the mantle, whereby it is protected from breakage orinjury.

. Since the parts e" are composed of chains of articulated members, theyare movable laterally in all directions. They cooperate with the elasticparts or springs, and thus assist in taking up shocks, jars, andvibrations, and in: the protection ofthe mantle. The presence oi' aweight, as k, is of importance because by reason of its mass itpossesses considerable inertia, which of course tends to protect themantle from sudden shocks and jars. The Washer and sleeve hand b2 notonly afford a seat into which the upper end of the flexible tube isloosely fitted, but also protect the same from heat, which might injureit if it were made of rubber.

ICO

It will be obvious to those skilled in the art to which our inventionappcrtains that niodiiicat-ions may be made in details withoutdepartingr from the spirit thereof. Hence we do not limit ourselves tothe precise construction and arrangement of parts hereinabove set forth,and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of our invention, what weclaim as new, and desire to secure by Letters Patent, is

l. In combination, a burner-cap suspended by antivibration connections,a base, inlets for admitting air near the base, and a flexible tubeinterposed between the base and cap and operating` both as a Bunsen tubeand as a flexible gas connection, substantially as described,

2. In combination, a burner-cap suitably suspended by antivibrationconnections, a sleeve depending from said cap, a base, inlets foradmitting air near the base, and a iiexible tube interposed between thesleeve and base and adapted for operation both as a Bunsen tube and aflexible gas connection, substantially as described.

In combination a mantle or hood, a mantle-carrier, elastic supports forsaid mantle or hood, and a weight connected with said carrier andsustained by said supports, substantially as described.

4f. In combination an antivibration incandescent or IVelSbach burner,and a weight applied to said burner, substantially as described.

5. In combination a mantle or hood, a mantle-carrier, elastic supportsfor said mantle or hood, flexible gas connections, and a weightconnected with said carrier and sustained by said supports,substantially as described.

G. In combination a gallery provided with a burnencap and a mantle orhood, elastic supports for said gallery, a weight applied to saidgallery, a sleeve depending from said burner-cap, a base, and a fiexibleBunsen tube applied to said base and itted to said sleeve, substantiallyas described.

In testimony whereof we have hereunto signed our naines in the presenceof two witnesscs.
